Frogs are not appreciated enough in my opinion, this is a very important thread.
Here is my ranking:
S - Drift. He’s adorable and he’s been my best friend since City Folk. I can’t actually remember why I liked him, I just did.
He’ll be my favourite villager forever 
A - I love these villagers, I’d invite them in a heartbeat.
Henry - I had in New Leaf and he’s so sweet!! I stopped playing in 2020 when he left
Wart Jr - I had him in my childhood City Folk town, and I thought of him as Drift’s friend.
B - Great villagers, I really like them.
C - Good. Croque doesn’t quite look appealing enough for B-tier, but I still like him. I had him in my New Leaf town.
D - Not exactly the best but I can deal with them.
Gigi - I had her for a little while early on in New Horizons. It was when she wore her Bunny Day egg costume that I realised her appearance ruins it all for her.
Diva - I had her in New Leaf and enjoyed her at the time, but now her eyes kind of scare me
F - I don’t really want them.
Raddle - I’ve never met him. The other frogs seem really happy but Raddle is just sad. He doesn’t fit the mood.
Jambette - The lips.
I just used the frogs from this general link, let’s see your thoughts!
